Source:
E. coli
Form:
The sterile ?ltered solution was lyophilized without additives.
Purity:
(same/more than) 98% by SDS-PAGE and HPLC.
Endotoxin:
(same/less than) 0.1ng/ug (1EU/ug)
Biological Activity: Tested by its ability to suppress LPS-induced TNF-alpha and MIP-2 production in mouse splenocytes.
Reconstitution:
A quick spin followed by reconstitution in water to a concentration of 0.1-1.0mg/ml. This solution can then be diluted into other aqueous buffers and stored at 4 degrees C for 1 week or -20 degrees C for future use.
Storage and Stability:
Lyophilized protein is stable for a few weeks at room temperature, but best stored at -20 degrees C. Reconstituted IL-4 should be stored in working aliquots at -20 degrees C.
